Bio-digester toilet

–BY Manojni, Nikitha, Gulabi

A  green toilet complex has been started in Madurai (Tamil Nadu) in 2015. It functions with the bio-digester technology designed by DRDO. The bio digester technology was modeled on an eco friendly working model and eliminated the need of maintenance .

Anaerobic bacteria is feed into the bio digester tanks, which decomposes fecal matter into effluents & gas which are odorless. The bacteria need to be fed into the tanks only once at the start of the functioning .the bio-digester  do not emit odors in contrast to conventional septic tanks.

The bio-gas produced could simply be left off into the  atmosphere or used for cooking and in water heaters.
